To all whom it may concern Be it known thatlI, WILLIAiu MUZZY,

a citizen of the United States, residing at Dayton, in the county of Montgomery, and

State of Ohio, have invented certain'new and useful Improvements in Tractor- Swings, of which I declarethe following to be a full, clear, and exact description.

This invention relates to improvements in swings and has more particular relation to improvements in porch swings.

One of the principal objects of the invention is to provide a porch swing with means i for resting the feet which may be used to cause the swingto swing back and forth.

A further object is to so construct the swing as to give it a practically rigid back while still allowing the swing to be flexibly suspended. Y

The. invention also has other objects all of which will be apparent from the follow ing description and the accompanying draw ings in which latter:

Figure 1 represents a central vertical sec tion through the devices embodying my invention. of the same and, Fig. 3 represents a detail front elevation, partly broken away of the foot board, one of the tractors and its supporting bracket.

The base of the swing comprises a frame 1 which supports a mattress or seat 2 having any suitable springs, not shown. The frame is suspended at each end by canvas sides 8 which are secured about side rails 4 through which the supporting ropes 5 are passed; these ropes on each side converging to a ring 6 supported by a rope 7 which is secured to the ceiling of the porch.

The back rest 8 is a rigid frame suitably tufted and hinged at its lower edge to the rear edgeof theframe 1. The upper corners of the back are provided with pivoted hooks 9 which are arranged to hook over headed pins 10 in the side rails 4 to hold the back in position but allow of its being,

doubled down upon the seat 2 when desired to protect the tufting of the seat and the back from rain which beats in upon a porch at times.

The foot rail or board 11 is supported at each end by wire wheel 12 having a suitable f rubber tire and journaled on a bolt 12 which is secured to a bracket iron 13. These irons are secured byscrews to the under side of Fig. 2 represents a top plan-view TBAC'IORFSWING.

'the foot rail 11. Rods or bars are secured at their forward endsyto thefunder rigid back 8 and thecenter of gravity will be shifted to the rear which will cause the swing to swing forward. The operator naturally relieves the pressure on the foot rail 11 as-the swing swings forward and the swingreturns when the operation is repeated. A very slight pressure on the foot rail will cause the swing to gently oscillate and at the same time the feet are comfortably supported and not dragging on the fioor as is usual in this class of swing. Further, even though the operator isplaced near'one side of the swing and pushes on the foot rail near one end the swing will still swing true and not start a sidewise oscillation such as would occur if the operatorpushed on the -porch floor as at present in such swings.

The tractors or wheels 12 causethe swingto swing true at all times by their engagement with the porch floor. These wheels by resting upon the porch floor provide the neces-j I sary purchase for the feet of the operator,

to push against just as if he were pushing upon the floor itself and at the same time move with the swingso that the feet of the operator have a comfortable rest and are always ready for the pushing operation.

The location of. the foot rest in relation to the swing is such that when the swing swings to the rear the operators' legs are drawn together as in. rowing and he" straightens them out as the swing swings forward and can -thus exert considerable power without much exertion.

This actionis added "to the a It will, of course, be understood that the p I claim as new and desire to secureby Leta 10 ters Patent is:

The com-bin'ation'with aswing suspended to swing freely, of1a-fo0t board supported byspaced tractor wheels, spaced guide bars "'onthe foot board and so" connected to the swing as to be capable of vertical pivotal "movementpmy to prevent any side movement of the swing.

"In "testimony whereof I affix my signature in the presence of two witnesses.
